4 Claims. (01. 128- 283) 1 This invention. relates genera y to a stoma receiver and particularly to agreatly simplified assembly for converting a thin disposable bag into an efiicient colostomy appliance. i

It is an object of my present invention to .pro vide an extremely simple stoma receiver particularly adapted for easy manufacture and of relatively inexpensive construction. a

More specifically, it is an objectto proyide a stoma receiver assembly consisting in a highly flexible disposable bag structure having a pair of concentrically disposed annular clamping rings adapted to quickly and easily receivea portion of the rearlayer or" the bag therebetween in sealed, tightly clamped relation and having attachment means for mounting the outer ring onto the body of a wearer while positively. locking said rings in clampingposition. 2

These and other objects and advantages of my invention will more fully appear fromtheiollowing description made in connection. with v the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views and in which: 7

Fig. 1 is a perspective view showing a complete appliance embodyingmy invention in operative position on the body of a wearer; a Fig. 2 is a transverse vertical sectional view taken substantially through the center oi the structure shown in Fig. 1; I I

Fig. 3 is a transverse horizontal sectional view taken substantially through the center of the stoma receiving aperture of the apparatus shown in Fig. 2; and a I n Fig. 4 is a semi-exploded view showing the individual members of my appliance in separate perspective illustrations. As illustrated in the accompanying drawings, I provide an extremely simple and inexpensive colostomy appliance having a bag 8 made from any suitable thin, highly pliable waterproof material such as vinyl or polyethylene plastic sheet material. The upper end of the bag 8 is sealed, as indicated at 8a of Fig. 2. An outer annular retaining and mounting ring, shown in perspective in Fig. 4 and designated by the numeral 9, is provided and has a pairof pivotally mounted attachment hooks l0 each witha hook Illa on one end thereof and an inwardly extending locking cam Hlb on the other end thereof. An aperture 9a. is centrally formed Within ring 9. and has an annular clamping and sealing groove 9b which forms an annular shoulder 9c on the outer portion thereof. The inner surface of said ring 9 is smooth and is adapted to be disposed adjacent a body engaging absorbent pad. I I, as shown in Figs. 1 and 2. An annular clamping insert l2 having an external peripheral groove [2a forming a clamping shoulder 12b is also provided and is adapted to be 2 received within the central aperture of ring 9 with the shoulder lZb engaged against the shoulder to, as best shown in Figs. 2 and 3. The hooks l it are swung into retracted position, as shown in Fig. 4, to permit clearance for: insertion of the insert l2 therein.

, To assemble my colostomy appliance, the inner layer 8b of bag 8 may be provided with a round out outaperture 80, as shown in Fig. 4, and this aperture is slightly larger than the inner aperture of insert 12, as best shown in Figs. 2 and 3. The inner aperture of insertl? is smoothly contoured and rounded to prevent irritation to the stoma when engagedthereagainst during movement of the wearer. The insert I2 is slipped into the interior of the bag 8 and is positioned on the inside of the inner layer 81) with thesmoothly contoured aperture substantially aligned with the aperture to. The shoulder l2b of the insert I2 is of course facing inwardly, as best shown in Figs. 2 and 3. The ring 8 with the shoulder 9c facing outwardly is then mounted over the insert l2 on the outside of the inner bag layer with the inner periphery of the aperture 9a in closely surrounding relation to the outer periphery of the insert l2 with the shoulders I21) and 9c tightly clamped together with the thin sheet material of the rear bag layer interposed in sealed relation therebetween. The camming hooks III are then swung into insert locking position, as shown by the full lines of Fig. 4,,and also shown in Fig. 3. The camming ends Illb are smoothly contoured to prevent injury or tearing of the engaged portion 01 the bag and the hooks we are of course disposed on the outside of mounting and retaining ring 9, as best shown in Fig. 3. In Fig. 4, the inner layer 8b of the bag is viewed to show the innersurface thereof and the insert [2 is shown with the shoulder lib disposedin its normal position in inwardly facing relation and of course is inserted behind the inner bag layer 821 in the position illustrated. However, in order to more clearly/illustrate the peripheral groove 9b and shoulder 90, the attachment and retaining ring 9 is shown in inverted position with the outer surface presented for View. 'In order to assemble my appliance, the ring 9 must be turned aro'undto face the outer surface containing the hooks Ill and adjacent the shoulder toward the outside of the structure.

Any suitable means may be used for closing the lower end of the bag, such as a flexible, cylindrical clamping roll 13 and'resi'lient clip 14, as best shown in Fig. 1. Also, the two belts .15 and l6 may b'eattache'd in any conventional manner at their ends to the respective hooks ID as" by the attachment elements [1.

It should be noted that the insert ring [2 is substantially thicker than the mounting and reta'ining ring 9' and that the shoulder [2 b is disposed substantially adjacent the outer surface of said ring l2, that is the surface disposed with in the bag 3, thereby positioning the inner smoothly contoured surface in protruding relation relative to the ring 9, as shown in Figs. 2 and 3. When the two rings are in assembled position, this protruding of the insert ring i2 toward the body of the wearer forms a pressure boss surrounding the stoma and forms a rela tively tight seal against the pad H to securely hold the same around the stoma and permit limited tilting of the ring assembly unit while maintaining a sealing pressure around the stoma. The insert ring if, due to the resiliency of the plastic material of the bag 8, may be inserted through the aperture to and positioned inside of the bag adjacent said aperture and the outer mounting and retaining ring clamped thereagainst in the manner previously described.

It will be seen that I have provided an extremely simple colostomy appliance particularly adapted for inexpensive manufacture and sale and providing only a minimum of separate parts while producing highly efiicient results. The simplicity of design of my invention disclosed herein is an extremely important part of the inventive concept thereof since only two separable coopcrating clamping members are provided to securely attach and seal the upper portion of a bag of the inexpensive disposable or semi-disposable type in operative position surrounding the stoma of the wearer while providing a smoothly contoured stoma surrounding opening to prevent irritation of the stoma upon intermittent contact therewith.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without .eparting from the scope of my invention which, generally stated, consists in the matter shown and described herein and set forth in the appended claims.
